Absolutely. Using a 120V extension cord, properly sized for the load, on a 120V circuit is perfectly acceptable. Do be aware of making sure the wire is run in a physically safe manner (such that it won't be pinched, abraded, enclosed in thermally insulating materials, stapled through, etc.)
The voltage drop using the wire on 120V is a tenth what it would be for the same power transfer at 12V (because the current is one-tenth as great). The power loss is one one-hundredth as great, since that's voltage drop multiplied by the current. This same basic principle is the reason why power companies use high voltage transmission lines: it reduces line losses to an acceptable level.
